LINT-REMOVER FOR ELECTRICAL WAR? STOP-MOTION S.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application led May 6, 1908. Serial No. 431,236.

To all whom it may concern:

Be it known that I, EDMoND CHAMPAGNE, Jr., citizen of the United States, residing at Albion, in the county of Providence and State of Rhode Island, have invented new and useful Im rovements in Lint-Removers for Electrical arp Stop-Motions, of which the following is a specification.

My invention relates to lint-removers for electrical warp stop motions, of the type embodying a contact-roll, drop-bars or detectors suspended on warp threads and each adapted in the event of its warp thread breaking to coo erate with the contact-roll and close an e ectric circuit, and thereby put in operation a spring-actuated ship er or other means for stopping the loom, an means for wiping deposits oI lint or the like from the contact-roll on rotation of said roll.

One object of my invention is to provide in combination with the contact-roll in circuit closing means such as described, means arranged to derive motion from a working part of a loom and to turn the contact-roll, lncidental to operation of the loom, a ainst means for removing lint from said rol this being advanta eous inasmuch as it assures the contact-rol presenting a clean surface to any drop-bar or detector that may fall and recludes the possibilit)T of lint on the roll eing ired by an electric spark due to poor contact.

Another object of the invention is to provide means arranged to be operated by a working part of the loom and to rotate the lint-removing means during the working of the loom so as to increase the efficiency of said lint-removing means by presenting a fresh surface thereof at frequent intervals to the contact-roll.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are read 1n connection with the drawings, accompanyin and forming part of this specification, inw ich:

Figure 1 1s a view, partly in elevation and partly in vertical section of so much .of aloom as is necessary to illustrate the application of my improvements, it being understood that genera ly speakinlthe loom 1s constructed 1n the ordinary well own manner. F1 2 1s a section taken in the plane indicated y the line 2-2 of Fig. 1; and showing the toothed warp beam and toothed wheel not shown in Fig. 1 Fig. 3 is a perspective view illustrating the electrically controlled means for utting the shipper in operation i. e., enabIing the lay of the loom to knock oii' the shipper.

Similar letters of reference designate corresponding arts in all of the views of the drawings, referring to which:

A A are the frame sides of the loom to which are connected brackets B, carrying lease rods C over and under which warp threads are alternately passed, as usual. Disposed below the lease rods and secured between the frame sides A are parallel circuit bars D, and suspended from the warp threads and resting in engagement with the circuit bars are drop-bars or detectors E, which latter are designed in the event of the warp threads breaking to gravitate and touch the contact roll F which is located below the dro -bars in the manner clearly illustrated in ig. 2. There is one drop-bar or detector to each warp thread, and the circuit bars D are electrically connected through the loom frame and other means with one pole of a battery or other source of electric energy G', while the contact roll F is electrically connected with the other pole of said battery. In the electrical circuit with the bars D, the contact roll F and the battery G is a suitable electro-mechanical device H, preferably an electro-magnet, which is desi ned when the normally open circuit is close by the breaking of a warp thread and the falling of the drop-bar complementary to said thread against the contact roll F, to move an armature lever I and thereby raise a latch J connected with said lever into the path of a dager on a lay (not shown), so that on the folowing stroke of the lay the dagger will strike the latch and a knock-off K connected with the latch and through the medium of the said knock-ofi will strike a shipper L and disengaging the same from a notch in a guideplate M will permit the shi per to spring inn ward and operate the belt siilfter in the usual manner to stop the loom.

In carrying out my invention I provide of a revolution incidental to each revolution of the Wheel M.

I prefer to drive the wheel M from the warp beam P of the loom, and when expedient to connect the warp beam with the said wheel through the medium of intermeshed spur gear teeth c and d on the beam and wheel, respectively. I would have it under stood, however, that when my invention is applied to a loom, the warp beam of which has no spur gea1teetl1,any suitable driving connection may be provided between the beam and the wheel to rotate the latter' by the former.

By virtue of the contactroll F being turned as stated during the working of the loom, it will be manifest that a wiper in enga ement with the periphery of the contactrol will be enabled to keep the said periphery clean and free from lint so as to assure a perfeet contact between the roll and one of the drop-bars when the latter drops on the former, and in this connection I would have it distinctly understood that any suitable means may be employed for wiping the contact-roll F, without involving departure from the scope of my invention as deiined in the claims appended. I prefer, however, to employ for wiping the contact-roll, a roll S the periphery of which may be equipped with wiplng means such for instance asa textile coverlng e. The said roll S is preferably provided with teeth f and is preferably rotated by the engagement of the before-described tappet b with the said teeth f It will thus be seen that during the operation of the loom, first the contact-roll F and then the wiping roll S will be rotated but in op osite directions, with the result that the ro l S will positively o crate to remove lint from the periphery of tllie roll F. It will be noticed in this connection that different parts of the eriphery of the roll F are presented to dlfferent parts of the roll S, which obviously conduces to the entire eriphery of the roll F being kept entirely cliean.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In lint removing means for electrical warp stop motions, the combination with the contact-roll of circuit closing means, a roll for wiping the contact-roll, a Working part of the loom, and means intermediate the said working part and the contact-roll and wiping roll for rotating said rolls by movement of said part.

2. In lint removing means for electrical warp stop motions, the combination with a contact-roll having teeth at one end, and means for wiping the said roll, of a warp beam, a wheel, means on the wheel for engaging the teeth of the contact-roll and turning the latter, and a driving connection intermediate the warp beam and the wheel.

3. In lint removing means for electrical warp stop motions, the combination with a contact roll comprised in circuit closing means and having teeth at one end, and a roll for wiping thecontact-roll also having teeth at one end, of a warp beam, a wheel, means on the wheel for engaging the teeth of the contact-roll and the teeth of the wiping roll and turning said rolls in opposite directions, and a driving connection intermediate the warp beam and the wheel.

4. In lint removing means for electrical warp stop motions, the combination with a contact roll comprised in circuit closing means and having teeth at one end, and a roll for wiping the contact-roll also having teeth at one end, of a warp beam, a wheel, a driving connection intermediate the warp beam and the wheel, and a tappet on the wheel arranged to engage the teeth of the said rolls and turn the rolls in opposite directions.

5. In lint removing means for electrical warp stop motions, the combination with the contact-roll of circuit closin means, of a roll for wiping the contaet-ro l having teeth at one end, a warp beam, a wheel, a driving connection between the warp beam and the wheel, and means on the wheel for engaging the teeth of the wiping roll and rotating the latter.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
